Left Waiting and angry.

I would give zero if I could. I just received my invoice for June. I have been billed for a service I did not receive the sim and device for. I have just spoken to a very nice call center person. All of the call center people seem to know what is being asked of them and seem to know what they are talking about. However everything is always referred to the people who will action the request, the back office, this is where it all goes very wrong. This is where time is wasted waiting (3 to 7 days) for callbacks and responses that seem never to come until you call them back. I am still waiting for the promised callback from my previous Hello Peter review.
